Today, solar panels are more and more efficient and similar. It complicates our task because we don’t always know which one is best for our project.
To help you compare them, We have prepared this guide for you. We are going to tell you which are the best 50 Watt solar panels specifically. That way, you will have a concrete idea of what is being done on the market.
After reading this guide, you will also know what criteria to take into account when comparing panels with each other:
Photovoltaic yield
- The power
- Guarantees
This will allow you to know which product meets your needs.

Conclusion
The efficiency of a solar panel defines its power generation from sunlight. In other words, a panel with a good efficiency will produce more energy for the same surface. This is an important criterion if your place is limited. Technically, the yield mainly depends on the type of cells used. As such, monocrystalline are more efficient (16 to 25% yield) than polycrystalline (14 to 18%). Today, there are almost only “mono” panels, which are very competitive in terms of quality/price ratio. A “poly” module concerns an old generation product.
This time, it’s the performance that you are guaranteed after the first 25 years of operation. We advise you to choose a module that does not fall below 80%, or even 85% if possible. The new solar panel technologies and innovations are applied new produced products that can help you to reduce your electricity consumption even lower.
The more the years go by, the more manufacturers set themselves thresholds of excellence. So don’t worry, it is rare today to buy panels with less than 80% yield over 25 years.
What criteria should be used for its solar panels?
Criteria to remember: Well before the question of the choice of equipment, it is rather the overall installation that must be considered:
What are my photovoltaic panels going to be used for?
- to provide income.
- to cover part of my consumption.
- to produce as much solar energy as possible.
- to be autonomous.
How much power do I need to meet this objective?
- What space do I have?
- Which solar panels meet these constraints?
- And at what price?
- Consult our articles dedicated to the profitability and sizing of the power of photovoltaic modules to find out more.
Price: an important factor
Although it is not the only factor that will determine the choice of solar panel, the price plays an important role in the profitability of your project.
For this, the solar panel must include a quality/price ratio that allows you to make your installation profitable as quickly as possible.
Solar panel prices depend, among other things, on:
- their strength;
- their product and performance warranties;
- and the technology used.
